This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers. The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences. As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again! We are better
off marking them as wakeup-capable and leaving wakeup disabled.Signed-off-by: Alan Stern

This patch (as1193b) enables wakeup during initialization for all PCI
host controllers, and it removes some code (and comments!) that are no
longer needed now that the PCI core automatically initializes wakeup
settings for all new devices.The idea is that the bus should initialize wakeup, and the bus glue
or controller driver should enable it.Signed-off-by: Alan Stern

usb: ohci-sm501 driver V2
This patch adds sm501 ohci support. It's all very straightforward with the
exception of dma_declare_coherent_memory() and HCD_LOCAL_MEM. Together they
are used to ensure that usb data is allocated using dma_alloc_coherent(),
and that only valid dma memory is used to allocate from. This driver is
a platform device, and the mfd driver sm501.c is already creating one
usb host controller instance per sm501.Signed-off-by: Magnus Damm

The OHCI driver's IRQ handler, while processing a WDH interrupt, masks
and unmasks it. I believe this is both broken (the write may still be
posted during the donelist processing it's trying to safeguard) and
useless as this IRQ may not be reissued until it's acked (unless this
legacy code is an uncommented workaround for some chip erratum).Signed-off-by: Benjamin Herrenschmidt

The OHCI IRQ handler has an optimisation that avoids reading some
chip registers when the controller reports that the interrupt was
triggered *only* because completed requests were written into the
controller's "done list" and handed to the host.This mechanism can't be used on some controllers. Among others, it
fails for the SA1111 and the AMCC 440EP PowerPC processor.This patch removes the optimisation and makes the code clearer.

This patch (as975) reorganizes the way ohci-hcd sets urb->status. It

This patch (as954) implements a suggestion of David Brownell's. Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues. This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't. It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler. For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back. A few HCDs make
matters more complicated by the way they split up the flow of control.In addition some method interfaces get changed. The endpoint argument
for urb_enqueue is now redundant so it is removed. The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.Signed-off-by: Alan Stern

The ZF Micro OHCI controller exhibits unexpected behavior that seems to be
related to high load. Under certain conditions, the controller will
complete a TD, remove it from the endpoint's queue, and fail to add it to
the donelist. This causes the endpoint to appear to stop responding. Worse,
if the device is removed while in that state, OHCI will hang while waiting
for the orphaned TD to complete. The situation is not recoverable without
rebooting.This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag:
1. A watchdog routine periodically scans the OHCI structures to check
for orphaned TDs. In these cases the TD is taken back from the
controller and completed normally.2. If a device is removed while the endpoint is hung but before the
watchdog catches the situation, any outstanding TDs are taken back
from the controller in the 'sanitize' phase.The ohci-hcd driver used to print "INTR_SF lossage" in this situation;
this changes it to the universally accurate "ED unlink timeout". Other
instances of this message presumably have different root causes.Both this Compaq quirk and a NEC quirk are now properly compiled out for
non-PCI builds of this driver.Signed-off-by: Mike Nuss

This patch (as887) changes the way ehci-hcd and ohci-hcd handle a loss
of VBUS power during suspend. In order for the USB-persist facility
to work correctly, it is necessary for low- and full-speed devices
attached to a high-speed port to be handed back to the companion
controller during resume processing.This entails three changes: adding code to ehci-hcd to perform the
handover, removing code from ohci-hcd to turn off ports during
root-hub reinit, and adding code to ohci-hcd to turn on ports during
PCI controller resume. (Other bus glue resume methods for platforms
supporting high-speed controllers would need a similar change, if any
existed.)Signed-off-by: Alan Stern
